The EAW RSZ3t is a classic electromechanical thermal overcurrent protection relay with time-dependent operation, intended for applications in electrical protection and control systems.
Its mechanical construction, adjustment scales, electrical contacts, internal components and original identification markings represent the traditional relay technology used before modern electronic and digital protection systems became widespread.
The RSZ3t is therefore of potential interest not only as an electrical component, but also as a piece of historical industrial technology.
EAW equipment forms part of the history of German electrical engineering and industrial electrical equipment of the former GDR.
The RSZ3t is representative of classic electromechanical relay technology used in electrical protection applications.
References to the period around 1970 describe the historical period associated with the model/design and do not certify the exact manufacturing year of this particular unit.
The relay has been stored as a spare component and has not been used in normal operation.
The original housing, transparent front cover, scales, markings, adjustment indicators and visible internal components are preserved.
Because this is historical equipment, minor signs of age or storage may be present. Please examine all photographs carefully.
The photographs show the actual EAW RSZ3t relay offered in this listing.
Please review the photographs for the exact cosmetic condition, markings and configuration of the item.

This is historical electromechanical electrical equipment.
Although the item is unused, unused does not mean electrically tested or certified for modern installation.
Before connecting, energizing or installing the relay in any electrical system, the buyer should have the unit professionally inspected and verify the technical specifications, wiring diagram, contact condition, adjustment settings, insulation condition, electrical characteristics and compatibility with the intended system.
Professional inspection and testing by a qualified electrical specialist is strongly recommended before any practical electrical application.
